BAIL-ANCHOR.

Specification of Letters Patent. Patented May 18, 1915.

Application filed August 26, 1914. Serial No. 858,645.

To all whom it may concern Be it known that we, ADoLPH H. SMITH and GEORGE l/V. NIBBE, citizens of the United States, residing at Chicago, in the county. of Cook and State of Illinois, have invented certain new and useful Improvements in Rail-Anchors, of which the following is a specification.

Our invention relates in general to railway track fastening devices, and more par-V ti'cularly to rail anti-creepers. lit is well known that the passage of trains over railway tracks tends to shift the tracks longitudinally in the direction of the movement of the trains. When the trains run in opposite directions on the same tracks the tendency of the tracks to creep in one direction is compensated by their tendency to creep in the opposite direction, but when the trains run only in one direction, as is the case with double track roads, the creeping or shifting of the rails is so considerable as to be dangerous unless prevented.

lhe primary object of our invention is to provide improved anchoring devices for railroad rails to prevent longitudinal creeping or shifting thereof, which will securely retain the rails against longitudinal movement relatively to the ties, and will be automatically actuated by any tendency of the rails to creep to grip the rails more securely and effect a more rigid resistance to the creeping tendency.

A still further object of our invention is to provide an improved anti-creeper for railroad rails which will be simple in construction, convenient in application, eflicient in operation, and durable in use.

Our invention will be more fully disclosed hereinafter with reference to the accompanying vdrawings, in which the same is illustrated in a convenient and practical form, and in which- Figure 1 is an elevational view showing our invention applied to a rail; Fig. 2 a perspective view of one of the clamping members; Fig. 3 a perspective view of the other clamping member; and Fig. i a plan view looking upwardly with respect to Fig. 1, showing the engagement of the clamping members beneath the rail base.

Reference letter A indicates a railroad rail, the base a of which is supported upon a tie B. p

C and D designate interlocking clamping members which are adapted to be secured to the base of the rail adjacent the tie B and to engage the tie to prevent the creeping of the rail toward the same. The clamping members C and D are provided with upwardly and inwardly extending flanges c and 0?, respectively, which are adapted to engage the opposite sides ofthe base a of the rail. The clamping members are provided with portions which transversely overlap beneath the rail base, and at the inner edges of such transversely overlapping portions are provided longitudinally overlapping parts G and H. The transversely overlapping portions of the clamping members C and D are cut away, as shown at e and 7, respectively, in order that such transversely overlapping portions may also longitudinally overlap to permit the depending longitudinally overlapped portions G and H to be longitudinally adjusted with relation to each other to the requisite degree to effect the gripping of the edges of the rail base by the flanges c and d of the clamping members. It will be observed by reference to Fig. i that the vertical contacting faces of the longitudinal overlapping parts G and H meet in a longitudinal plane slightly in clined from the longitudinal plane of the rail, in order that when said parts are relatively moved longitudinally into interlocked engagement, the clamping members will be drawn toward each other and thereby securely grip the rail base.

The contacting vertical surfaces of the longitudinal overlapping parts G and H are preferably serrated, as indicated at g and h,

' in order that the clamping members may be positively retained in the adjusted positions to which they may be forced in securing them tightly to the rail base.

One of the clamping members, as for instance D, is provided with a depending shoulder K, which bears against the adjacent surface of the tie B so that any tendency of the rail to creep toward the tie tends to move the clamping member C with it and relatively to the clamping member D owing to the latter being retained against such longitudinal movement by reason of the bearing of its shoulder K against the tie. Therefore, any tendency of the rail to creep toward the tie effects a more secure gripping of the clamping members with the rail base and consequently a more secure anchoring of therail with respect to the tie.

When the clamping members are in in terlocked engagement it will be seen that the end of the depending part H extends beneath the overlying portion E of the clamp ing member G, and also that the end of the ping relation. with the rail base.

depending part G extends beneath the overlying-portion F of the complemental clamping member 1).

Our improved anti-creeping. device may 'be readily applied to a rail'by engaging the clamping members with the rail base the clamping member D being located adjacent the tie l3 and with the shoulder K thereon bearing against the adjacent vertical surface" of the tie. Theidepending parts G and H are placed in longitudinally overlapped relation with their ends respectively underlying the portionsE ancl'F of therespective clamping members. The member C is then driven toward the tie so that the relative longitudinal movement of the depending parts G and Hwill, owing to the incli-' nation of the'plane'of their contacting sur faces to the'longitudina l plane of the rail, draw the flanges 0 and 0? into tightly grip From the foregoing description it will be'observed thatwe have invented an im- I proved anchoring device for preventing the What we claim is:

1. The combination with a railroad. rail and supporting tie therefor, of a pair ofclamping members engaging the opposite sides of the rail base comprising transversely overlapping portions extending'be neath the rail base, theends. of said overlapping portions having interlocking de-' pending wedge" elements.

The combination with a railroad rail and supporting tie therefor, of a pair of clamping members engaging: the opposite sides of the rail base comprising trans versely' overlapping portions extending beneath the rail base, the ends of said overlapping portions having interlocking depending wedge elements, and the slaidover lapping portions being cut away to permitthe relative longitudinal adjustment of said wedge elements.

3; The combination with a' railroad rail our names.

and supporting tie therefor, of a pair of clamping members engaging the opposite sides of the rail base comprising transversely overlapping portions extending be,- neath the rail base,'the ends of said overlapping portions having interlocking depending wedge elements, the end-'of each of said wedge elements, extending beneath the transversely overlapping portion of the other member.

rThe combination with a railroads-rail and. supporting tie there-for, of a pair of. clamping members engaging the opposite sides of the rail base comprising transv .versely overlappingportions extending beneath the rail base, the ends of said overlapping portions having interlocking wedge elements,'each of said'members having a chamber to receive theend'of the wedge element of the other member so asto permit therelative longitudinal adjustment of the wedge elements.

5. The combination with a railroad rail 1 and supporting. tie therefor, of a pair of clamping members engaging the opposite sides of therail base comprising transversely overlapping portions extending beneath the rail base, the ends of said overlapping portions having interlocking wedge elements,

the vertical contacting surfaces of which are provided with serrations. I

6. In a devlce for preventingthecreeplng of railroad rails, a clamping member comprising a flange to engage the-rail base, a

portion to extend beneath the rail base, and

a depending wedge element having serra tions on. the vert1cal surface thereof to -engage corresponding serrations on a. similar .wedge element of a cooperating clamping member. 7 7

7. In a device for. preventing the creeping of railroads rails, a clamping member comprising a flange to engage the rail base, a portion to, extend beneath the railbase, and a depending wedge element at thejwedge of said portion having serrations on the ver tical surface thereof toengage corresponding serrations on a slmilar wedge element of a cooperating clamping member, said porti'on being cut away to permit longitudinal adjustment of the clamping member rela-' tively to the cooperating clamping member.
